【摘要】 应用分子动力学方法模拟铜针尖原子在其基体上的摩擦过程 针尖原子的受力和以下参数有关:温度、接触面积、滑动速度.随着温度的升高,摩擦力增大;接触面积增大,摩擦力增大;针尖为软针尖、滑动速度小于一定范围时,随着速度的增大,摩擦力逐渐增大,当超过该范围时,随着滑动速度的增大,摩擦力反而减小.更多还原

【Abstract】 Molecular dynamics simulations of nanoscale sliding friction between tip and surface of copper shows that:the friction force is dependent on parameters such as temperature?contact area,sliding velocity and so on. The friction force increases with the increasing temperature and contact area. When the tip is soft, the friction force increases with sliding velocity when the velocity within the specific value, while bigger than that value, the force decreases.更多还原
